Originally broadcast Oct. 2, 2021. Gary Billings, who has been an amateur astronomer since the '90s, instructs this How-to Hour, which is a continuation of his September How-to Hour, "Information from Periodic Star Light Curves." (If you missed it, check out the recording at youtube.com/watch?v=eiivkjwTM-Q) or his slides (linked at aavso.org/2021-webinars-abstracts#o-c).
We now look at some of the ways that a star's behavior might vary from a constant period, and focus on simple calculations involving a star's period and period changes, but not the astrophysical causes of the period changes. While the principles apply to other types of stars, eclipsing binary stars are used as examples.
The previous Eclipsing Binaries How-to Hour is on information from Periodic star Light Curves: studio.youtube.com/video/eiivkjwTM-Q/edit
